Buckeye .... Cave Run is only down about 1ft from Summer Pool so launching shouldn't be a problem at most any ramp. Now, that level is subject to rising a bit if they get a couple inches of rain as forecast.
This link will show you the water levels : Louisville District Daily Lake Report
This link will show you the GPS coords of the habitat placed in the lake by the KDFWR : Cave Run Lake Fish Attractors - Google My Maps The map is interactive, so you can zoom in and see the placement areas, & types of cover used. Click on any of the habitat icons and get three formats of the GPS coords of that habitat spot. The format you use will depend on what brand depth finder you have & what format it uses.
I've always used the Alfrey Ramp or the Scott Creek Marina Ramp. There is a launch fee at those ramps (I think $5).
It's been quite a few years, but the last time I was there was in Oct. & Cassidy Ford Hollow was choked with moss. Most boats we saw were out in the middle of the lake, fishing the brushpiles there & along the shore of the Zilpo campground.
I'll defer any recommendations of areas to fish to those members that fish it regularly (or have recently fished there) as I have not been there for quite some time.
